J2EE
Interoperate, Enhance, Migrate
Make .NET Secure
Keep .NET Departmental
Protect Your Investment
The Productivity Sacrifice

Perceived Complex & Difficult
The Cost Comparison
 .NET
–
–
–
Microsoft Controls the Price
Microsoft Are Often Giving It Away
Purchase the OS, Server and Tools From One Vendor
 J2EE
–
–
–
At Least 30 Different Vendors
Purchase OS, Server and Tools From Many Vendors
Price Points From Free to Price Competitive to Microsoft and
Beyond

Complexity & Abstraction
Technology Drivers for J2EE and
.NET
 Internet Is Ubiquitous
–
All Users, Information, Applications On Internet
 Internet Becomes Programmable
–
Applications Conform to Service-Oriented Architecture
 Services are Seamlessly Integrated
–
To Automate Business Processes
 Services Becomes Accessible Ubiquitously
–
Anytime, Anywhere, Any Device via Portals
 Services Use Resources On-Demand
–
Network, Storage, CPU, OS Resource Virtualized to Grids

–
Tightly Integrate All Fine Grained Components
and Languages at Runtime
Loosely Integrate Heterogeneous Applications
With XML Web Services
Communicate Via XML
